SPRAYING-NOZZLE.

SVCIFICATION forming' part of Letters Patent NO. 625,466, datd May 23, 1899.

Application filed April 22, 1898. Serial N0. 678,481. (No model.)

To a/ZZ wwnt t may concern:

Beit known that LWILLIAM WBANDOLPH,

a citizen of the United States of America, re-

siding in New Rochelle, county of llestchester, in the State of New York, have invented a certain new and useful Improvement in Spraying-Nozzles, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to the construction of nozzles for spraying water or other fluids, and has for its object to provide a spraying-nozzle which will provide for a more even distribution of the spray over a circular core than has heretofore been practicable.

My spraying-nozzle belongs to the class in which the spraying of a fluid issuing through the nozzle with considerable velocity is effected by giving it a rotary motion in the nozzle, so that as it issues therefrom the motion of each particle of fluid is eected by the two forces, one tending to carry it forward and the other tending to throw it outward tangentiall y, and the result of the two forces being, as is well known, to throw the body 0f fluid into an expanding cone and rapidly break it up into spray; and my invention consists inusing in a nozzle in place of a single angular delector for giving rotary motion to the uid a series of concentric angular defiectors arranged to operate upon concentric bodies of fluid passing through the nozzle and to give to each body a direction resulting from thel two forces acting upon it, which will result in a more even and uniform distribution of the composite jet. Preferably I make the concentric deectors of progressively higher pitch from the center outward,so that the successive conical jets will be of progressively greater angle, and preferably also I provide, in addition to the concentric deilecting devices, a corresponding series of concentric delivery-nozzles through which the fluid passes after leaving the deflecting devices and before its issuance from the nozzle.

Reference is now had to the drawings, in which my invention is illustrated, and in which- Figure lis a side elevation of the nozzle constructed in accordance with my invention,

showing the character of the composite jet. Fig. 2 is a rear View of the inside of the spraying-nozzle. Fig 3 is a longitudinal section taken as on the line .fr 0c of Fig. 2; and Figs. 4, 5, and 6 are dissociated perspective views of the dei'lecting devices and their attachments.

A indicates a iluidconduit leading, as shown, to a valve-casing B, O indicating the valve-handle, and through the valve-casing and a pipe-section D to the nozzle, (indicated at F,) the outer casing of the said nozzle being, as shown, screwed `into a threaded enlargement E of the pipe D.

The nozzle, as shown, is at its outer end divided into three concentric nozzle-sections the walls of which are formed by the tubes F, G, and H, and at the base of each of these sectional delivery-nozzles is situated adevice vfor giving a rotary movement to the particular body of iuid passing into each nozzle-section. As shown and as conveniently constructed, the tube G is provided with an outwardly-extending flange G, fitting against a shoulder f of the tube F and formed with angular slots g', through which the fluid passes and by which it is given a rotary movement as it passes into the annular space between the tubes F and G. The tube H is provided with a similar base-flange H', fitting against the shoulder g at the base of the tube G and provided with angular deflecting slots h', which give the desired rotative movement to the fluid as it passes into the chamber between tubes G and H.

I is a circular block adapted to fit against shoulders h at the base of the tube H, and

formed with angular deflecting-slots ,which give the desired rotative movement to the fluid as it passes into the tube H.

It will be observed that I have shown the deflecting-slots t', h', and g' as of progressively increasing angularity, this being done so as to make the sides of the cones (indicated at I2, H2, and G2, Fig. l) of progressively greater angularity, the arrangement being potential and preferably such as to make the composite cone of substantially uniform density.

It is obvious, of course, that the eective agents in giving the fluid a rotary motion are the angularly-set walls separating the grooves 'h' g i and which may properly be considered ICO partitions, the partitions in the dierent sec- Y tions being of progressively greater pitch 01 angularity from the center outward.

3. A spraying-nozzle having two or more concentrically arranged delivery sections each provided with angularly-set deectorpartitions whereby separate concentric bodies of Huid issuing from the spraying-nozzle are given a rotary motion and concentric delivery'- tubes through which the rotating bodies of uid escape from the spraying-nozzle.
